摘要：

A functionalization method based on the impregnation of previously grafted pore-expanded SBA-15 is presented. The combination of tethered and mobile amino groups has led to a synergic effect, yielding samples with CO2 uptakes up to 235 mg CO2 per g (5.34 mmol CO2 per g) at 45 degrees C and 0.15 bar CO2 and high adsorption efficiencies.
